Bow-FACING OAR.

SPECIFICATION forming part of Letters Patent No. 537,616, dated April16, 1895.

Applicationiiled March 23, 1894. Renewed March 12,1895. Serial No.541,486. (No model.)

To all whom t may concern.-

Be it known that I, REINHOLD H. PAAR, a citizen of the United States,residing at Carthage, in the county of Jasper and State of Missouri,have invented certain new and useful Improvements in Bow-Facing Oars;and I do herebyfdeclare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the sam e.

My invention relates to improvements in oars for boats, which consistsin new and automatic feathering devices, to facilitate the operation ofthe same, in combination with appropriate actuating mechanism and novelfeatures of construction, which will be hereinafter described andpointed out in the claim.

The object of my invention is to provide an oar for row-boats, wherebythe oarsman can face the bow of his-boat, and operate the same plates.

with perfect ease; thus overcoming dangers in navigating crowded waters.

In the accompanying drawings similar letters of reference indicate likeparts in the several figures.

Figure l''' is a top plan view of my improved feathering oar. Fig. 2-Lis a side elevation of the same, attached to a section of the boat inposition for rowing. Fig. 3- is adetailed plan View of the sector andpivotal link. Fig. et-is a cross section of the same. Fig. 5- is adetail view of the hinge. Fig. 6 is a modification of the coupling forthe handle, and blade of the oar.

My invention consists of a frame which is composed of two flat plates A,B, and is secured by bolts or screws passing through said Said boltsalso hold in position the heels of the oar pivots, at the same timeseparate plates A, B, to allow for the operation of the segmental gearsL, which are secured to and form part of the oars. t

Secured to the top of the plates A are two posts K, K, for supportingthe feathering mechanism. Mounted on these posts are two sector gears H,H, having their rear ends reduced and slotted for the reception of thefeathering mechanism, which will be hereinafter more fully described.The segmental gears are secured to posts K, K, by means of a plate I.

The handle C shown partly in section in Fig. 2- is mounted on a pivotalbearing and securely held in position by means of a screw, the screwengaging a recess in the pivotal bearing, thus allowing the handle tohave a rotary motion. The opposite end D of theoar is also provided witha pivotal bearing similar to the one at C, for securing the oar shaft D,with its accompanying blade. Secured to and forming a part of saidhandle C, and oar shaft D, are brackets which have extensions or pins F,extending over the plates Aland B, at right angles to the oar shaft.

The pins F, extend through links Gr, pivoted in the slots in the reducedportion of the segmental gear Il', as is clearly shown in Fig. 4.

The oar frame is mounted ona hinge by means of a pin M. The bottom ofthe hinge is provided with a pin orlug N, being adapted to iit in anysquare or oblong oar lock seat, and having a hole in its lower endwhereby it may be fastened securely by a string or any other suitabledevice as oar locks are ordinarily fastened thus enabling the oarsman toremove it at pleasure.

In Fig. 6- it will be noticed that the arm of the sector whichterminates in a tube wherein the handle C, and blade shaft D, may beinserted. After the blade or shaft has been inserted the handle carryingthe pin F can be securely fastened in its proper place by screws. Thescrew O, projects partly through the tube and into a recess formed intothe blade or handle.

The operation of my device is as follows: The oarsman sits with his faceto the bow, manipulating the oars in ordinary manner, at the same timehaving the advantage of seeing his course. The power is communicatedthrough the medium of the gearing L, L, to the oar shaftD, from thehandle C. As the oarsman makes a return stroke he feathers the oar byturning the handle C, as in feathering an ordinary oar, therebymovingthe pin F in the pivotal link G, causing the saineto tilt-H shownin Fig. 4.-as it moves the sector gear, thus communicating the samemotion to the oar shaft D.

In constructing my improved oar great libertyzcan be used in theselection of material.

I propose to use wood for the handle proper,

oar blade and shaft, while the other parts can IOO having slottedreduced portions and the brackets at'the respective inner ends of thehandle and oar blade shaft working loosely I5 in the slots, whereby theoar may be feathered substantially as specified.

In testimony whereof I affix my signature be made of aluminium, brass,malleable iron or steel, without departing from the spirit of myinvention.

Having described my invention, that which 5 I claim as new, and desireto secure by Letters I Patent, is-

frame carrying the pivoted intergearing segments, the oar handle and oarblade pivoted 1o respectively to pintles forming part thereof, theintergearing segments pivoted above the before mentioned segments to theframe and REINHOLD H. PAAR.
